Connection fails
Connecting a calendar account aborts or ends with an error? Here’s the quick triage.
By error message
Section titled “By error message”| You see … | Cause & fix |
|---|---|
| ”Need admin approval” (Microsoft) | Your organisation blocks third-party apps — the most common case → three ways out |
| ”App blocked” / “not verified by your administrator” (Google Workspace) | Same topic on Google’s side → three ways out |
| ”Sign-in failed” (Apple / KSuite) | Almost always the wrong password: it needs an app-specific password, not your regular one → Apple, KSuite |
| ”Feed could not be added” (iCal) | Check the URL: reachable? Really an .ics/webcal address? Only HTTPS is accepted → iCal feed |
| Limit notice in the connect dialog | Your plan’s account limit is reached → Plans & limits |
When the sign-in just “doesn’t go through”
Section titled “When the sign-in just “doesn’t go through””- Picked the wrong account: with several Google/Microsoft accounts in the browser, watch the account picker — when in doubt, private window.
- Permission declined: removing checkboxes or declining in the consent dialog aborts the connection — repeat and confirm everything (why the permissions are needed).
- Pop-up blocker: the provider window sometimes opens as a pop-up — allow it briefly and retry.
Connected, but nothing happens?
Section titled “Connected, but nothing happens?”Then it’s not a connection issue but a sync one → Sync not working — checklist
